For years, scientists have known that acupuncture may help reduce inflammation. But how does it actually affect the body’s immune system?
A newly published study from researchers in China offers one of the clearest answers yet.
Using an advanced live-imaging microscope, scientists were able to watch thousands of immune cells moving inside living mice in real time. They observed that during inflammation, immune cells rapidly gathered into large clusters. After electroacupuncture at ST36 (Zusanli), those abnormal cell clusters became much less frequent.
Instead of simply measuring blood tests after treatment, researchers actually watched immune-cell behavior change as it happened.
Why Is This Exciting?
Most previous acupuncture studies measured things like:
- Pain scores
- Inflammatory markers
- Brain activity
This study did something different.
Scientists directly observed how immune cells coordinated their movements inside a living body—something that wasn’t possible until recently because of advances in imaging technology.
What Does It Mean?
The findings suggest that electroacupuncture may influence communication between the nervous system and the immune system, helping regulate the body’s inflammatory response.
While researchers are still learning exactly how these pathways work, studies like this provide valuable biological evidence supporting what many previous acupuncture studies have suggested.
What It Doesn’t Mean
It’s important to keep the findings in perspective.
This study:
- Was performed in mice, not humans.
- Investigated electroacupuncture, not manual acupuncture.
- Does not prove acupuncture treats every inflammatory disease.
- Does not prove the existence of anatomical meridians.
Like many laboratory studies, it provides an important piece of scientific evidence while pointing toward future research.
Why Patients Should Care
Every year, researchers learn more about how acupuncture interacts with the body.
This study doesn’t change how acupuncture is practiced overnight, but it helps explain what may be happening at the cellular level during treatment.
At Metro Acupuncture, we follow both traditional East Asian medicine and modern scientific research to provide evidence-informed care for our patients.

The findings were published in Nature Biotechnology: Nature News: Electroacupuncture activates neurons to switch off inflammation.
Note: This study was conducted in mice using electroacupuncture. More clinical research is needed to determine how these findings translate to human patients.
